    Generalize set-matrix to have index limits · 33d52a9f

    Index limits may be passed to set-matrix and to some of the functions
    dependent on it, so that e.g. a tridiagonal matrix can be defined
    without iterating over all elements.  If the optional argument
    'pass-element is non-NIL, the function will be passed a final argument
    which is the prior value of the current element.
